Phishing Is Still the #1 Attack Vector — Here's How AI Fights Back

The Phishing Problem

Phishing is the practice of sending fraudulent emails that resemble emails from reputable sources. The aim is to steal sensitive data, such as credit card numbers and login information.

It is the most common type of cyberattack.

You can help protect yourself through education or a technology solution that filters malicious emails. SHANGO provides both.

Why Traditional Filters Fail

Rules-based email filters catch known patterns but miss:

Spear phishing (targeted, personalized attacks)

Business email compromise (BEC)

Novel phishing techniques

Attacks that use legitimate services (Google Docs, OneDrive)

How SENTINEL Uses AI

SENTINEL employs behavioral analysis that goes beyond rules:

Sender reputation scoring — Beyond simple domain checks, analyzing communication patterns

Natural language analysis — Detecting urgency manipulation and social engineering

Link destination prediction — Analyzing where links actually go before anyone clicks

Attachment sandboxing — Executing attachments in isolated environments

Cross-reference intelligence — Real-time threat intelligence from global feeds

The result: phishing attempts are caught before they reach your inbox — not after the damage is done.

Education + Technology = Defense

The best defense combines AI detection with human awareness. SHANGO provides both:

SENTINEL catches sophisticated attacks that bypass rules

Security awareness insights help your team recognize what AI might miss
